A power rectifier is a device that converts an alternating current (AC) into a direct current (DC) to power electronic devices. The term power rectifier is often used interchangeably with terms such as rectifier diode, power diode, and switching diode. These terms refer to the same type of device, which is commonly used in power supplies, battery chargers, and other electronic applications where DC power is required. Other synonyms for power rectifier include solid-state rectifier, high power rectifier, silicon rectifier, and bridge rectifier. These different terms refer to variations of the basic power rectifier design, which is essential for many electronics applications.
